You are talking about the river car dazao, right? I think it depends on your constitution, if you eat together without any reaction of fire, you eat together, antler gelatin as a dietary supplement, eat a small spoonful every day before bedtime should not be a big problem.
But I don't think it's better to take the Colla Corii Asini. It's just that the price of Colla Corii Asini has gone up wickedly, and I used to eat Colla Corii Asini for a while and thought it was great.
I hope this helps.
